Due to the complexity of the cell jitter, the NonSynchronous Tining Recovery methods are currently not mature With the emphasis being given to the Class A CBR traffic, this paper analyzes the performance of the queueing delay and cell jitter at the source node and intermediate nodes, and discusses the Source Timing Recovery at the destination node in ATM networks Firstly, this paper presents a description of the cell jitter of CBR traffic, and gives the definitions of two kinds of cell jitter regarding the Source Timing Recovery for CBR traffic Then, by using exact mathematical models and analysis methods, this paper analyzes the impact of the factors, such as the capacity of the queueing buffer, the randomness, the deterministic nature and the correlation in cell arrivals of the background traffic sources, on the queueing delay and cell jitter performance of the CBR traffic through Statistical Multiplexitng To obtain an insight into the power spectral distribution and look for better schemes for the depression and filtering of the cell jitter, within the analyses we succeed deriving the power spectrum of the cell jitter for CBR traffic Hence, not only the power spectral distribution of the cell jitter can in the frequency domain be qualitatively understood, but also can the rms (root-meansquare) value of the cell jitter be quantitatively obtained so as to more accurately measure the amplitude of the jitter In the end-to-end performance analysis of the queueing delay and cell jitter, we propose a kind of quasi-periodic cell stream model to characterize the jittered CBR traffic, and present an initial queueing analysis of the CBR traffic following such a model at a generic intermediate node Additionally, we briefly discuss the buildout/playout and Source Timing Recovery functions of the destination node Finally, regarding the Source Timing Recovery of CBR traffic, this paper systematically discusses several important principles of the cell jitter filtering and depression reported in the literature, introduces several implementation schemes of the Source Timing Recovery e.

由于信元抖动的复杂性,非同步定时恢复方法目前还很不成熟。本文针对A类CBR业务流在ATM网络源节点和中间节点的排队时延和信元抖动性能,以及在目的节点的源定时恢复问题作了较为全面的研究。首先,文中描述了CBR业务流的信元抖动,并具体地给出了两种与CBR业务源定时恢复有关的信元抖动的定义。然后,采用了精确的数学模型和分析方法,有针对性地分析了业务背景中信元到达的纯随机性、确定性和相关性以及排队缓存器容量等因素对CBR业务流经过统计复用后的排队时延和信元抖动性能的影响。为了了解信元抖动的功率频谱分布和寻求更好的抑制和滤除抖动的方法,在性能分析中,我们成功地完成了CBR业务流信元抖动的功率谱分析,使得不但可以从频域定性地认识信元抖动的能量分布特性,而且还可以定量地求出信元抖动的均方根值(rms:root-mean-square),以更为准确地衡量抖动的大小。在CBR业务流的多节点端-端排队时延和信元抖动性能分析中,我们提出了一种准周期性(quasi-periodic)信元流模型来描述感染了信元抖动的CBR业务流,并基于这一模型进行了CBR业务流中间节点的初步排队分析。

The animal model of this method system have, the characteristics of the high fat, high leptin, high Ins, and match with the characteristic of clinical and the pathologic of simple obesity. This studies showed: The acupuncture can obviously reduce the vaule of intaking food and water of the fat rats, and lower the body weight and fat; The acupuncture can urge the diameter, area, physical volume of white fat cell contract, Brown fat tissue of fat rat group surroundings vascular containing large quantity of white fat cell, the acupuncture group was less. this showed: The acupuncture enhanced the white fat cell metabolism, and promotesed the white fat cell to convert to brown fat cell; The frequency of spontaneous electric of nerve cell of pvn of the fat rat is high, the acupuncture counld depress the spontaneous electric of nerve cell of pvn, This showed: the acupuncture can depress the appetite passing to adjust function of pvn nerve; The monoaminergic neurotransmitter of inside of the fat rat brain is disfunction, the acupuncture can rectify this disfunction, and adjust level of 5-HT, and affect appetite, and improve metabolism; The level of leptin and Ins of fat rat increased high, The level of it of acupuncture group decreased, compared with the fat group p.001, This showed: the fat rats have the defeat of leptin and Ins in the body, The acupuncture can lowering this defeat, The level of leptin and Ins of the fat rat in the brain is less than the normal group, The level of leptin of the acupuncture group is high than the fat group, This showed: the acupuncture can increase the transportation of leptin from blood to brain.

本方法所制肥胖大鼠模型具有高体重、高脂、高leptin和高Ins血症的特点,符合人类单纯性肥胖病的临床和病理特征;实验研究显示:针灸能明显减少肥胖大鼠的摄水、摄食量及降低其体重、体脂;针灸能促使白色脂肪细胞直径、面积、体积缩小,减少肥胖大鼠棕色脂肪组织血管周围白色脂肪细胞数量,显示:针灸增强了白色脂肪细胞的代谢,促进了白色脂肪细胞向棕色脂肪细胞的转化:肥胖大鼠PVN神经细胞自发放电频率增加,脑内单胺递质紊乱,针灸通过抑制PVN亢奋的自发放电,调整5-HT水平,达到影响食欲,改善代谢的作用;肥胖大鼠血中leptin及Ins水平增高,与正常组大鼠比有明显差异,提示大鼠体内存在leptin及Ins抵抗,针灸后肥胖大鼠随着体重体脂的下降,血中leptin、Ins水平降低,与肥胖组比均有显著性差异,而针灸后大鼠脑内leptin增加,与肥胖组比P.05,提示:针灸具有改善leptin、Ins抵抗及增加leptin脑内转运的作用。

1、Cur inhibits K562 cells growth and induces cell apoptosis may be correlated with the down-regulation of p210~、inhibition of protein tyrosine phosphorylation and the signaling molecules such as p-Erk1/2、c-myc which are relevant with cell growth and apoptosis; 2、Cur synergizes STI571 to inhibit K562 cell growth and induce cell apoptosis may be correlated with the down-regulation of p210~、inhibition of protein tyrosine phosphorylation and the signaling molecules such as Hsp90、PKC which are relevant with cell growth and apoptosis; 3、Cur reverses the resistance of K562/G01 cells to STI571, and synergizes STI571 to inhibit K562/G01 cell growth and induce cell apoptosis; 4、Cur inhibits human originated CML CD34~+ cell growth、induces cell apoptosis, and enhances STI571 to down-regulate the expression of p210~, finally inhibit cell growth and induce cell apoptosis.

从以上实验结果我们得出如下结论: 1、Cur抑制K562细胞增殖、诱导细胞凋亡的作用可能与其下调p210~、蛋白酪氨酸磷酸化水平以及抑制下游p-Erk1/2、c-myc等信号分子有关; 2、Cur协同STI571抑制K562细胞增殖、诱导细胞凋亡的作用可能与其下调p210~、蛋白酪氨酸磷酸化水平以及抑制Hsp90和下游PKC等信号分子有关; 3、Cur可逆转K562/G01细胞对STI571的耐药性,并与STI571协同抑制K562/G01细胞增殖和诱导凋亡,其抑制K562/G01细胞增殖、诱导细胞凋亡的作用可能与其下调p210~、蛋白酪氨酸磷酸化水平以及抑制下游Procaspase-3和NF-κB等信号分子有关; 4、Cur可抑制来源于CML患者骨髓的CD34~+细胞的增殖并诱导其凋亡,还可协同STI571下调CML CD34~+细胞p210~表达,进而协同抑制细胞增殖、诱导细胞凋亡。
